Taking user input from HTML form as a variable for Python script – Twitter API

I’m creating a web app in Python/Flask to display tweets using twitters API using tweepy. I have set up an HTML form, and have got the script that finds the tweets with a certain input, currently, this is hard coded. I want the users to input a hashtag or similar, and then on submit, the script to run, with that as its parameter

I’ve created a form, with method GET and action is to run the script.

<form class="userinput" method="GET" action="Tweepy.py">
    <input type="text" placeholder="Search..">
    <button type="submit"></button>
</form>

I dont know how I would get the users input and store it in a variable to use for the tweepy code, any help would be greatly appreciated

    templates/index.html

    <form method="POST">
    <input name="variable">
    <input type="submit">
</form>

    app.py

    from flask import Flask, request, render_template
app = Flask(__name__)

@app.route('/')
def my_form():
    return render_template('index.html')

@app.route('/', methods=['POST'])
def my_form_post():
    variable = request.form['variable']
    return variable

    I guess you have set up and endpoint to run that script, an URL mapped to a function. In that case you need to call it from the form action.

    for example

    @app.route('/my-function')
def your_function(parameters):
    "code to do something awesome"
    return "the result of your function"

    So, in your form you should:

    <form class="userinput" method="GET" action="/my-function">
    <input type="text" placeholder="Search..">
    <button type="submit"></button>
</form>

    That should do the trick.

    Go to the Flask home page for more examples.
